Salmakk was a Mon Calamari smuggler and pirate active during the time of the Galactic Civil War.
Salmakk conducted his operations from the icy world of Hoth sometime before 2 ABY. When Han Solo arrived on Hoth to save his comrade Luke Skywalker, who had suffered a crash landing on the frozen planet, Salmakk decided to try and claim the bounty that Jabba the Hutt had put out for Solo's capture. Solo managed to evade capture, and he caused a cave-in that trapped the Mon Calamari in his base, which was located inside a hollowed-out mountain. After spending almost two standard days freeing themselves, Salmakk and his crew dismantled their operation and departed from the Hoth system.
The Rebels then took control of what was left of his base. Major Kem Monnon and the Alliance Corps of Engineers significantly enlarged the facilities, transforming Salmakk's old base into Echo Base.
In 5 ABY, Trioculus hired Salmakk and his pirate crew to attack warehouses situated on Cloud City.
